Application filed July 29, 1904. Serial No. 218,687.

To all whom it may concern.-

Be it known that 1, "WILLIAM B. RUNBEOK, acitizen of the UnitedStates,residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Fire-Hose Nozzles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in hose-nozzles, and particularlyto such as are especially adapted for use on fire-hose.

The object in view is the provision of means for producing a lateralspray for protecting the person supporting the nozzle from the action ofthe flames, and this object is obtained by the employment, incombination with a nozzle-section formed with lateral apertures, of atubular section longitudinally movably connected with saidnozzle-section and extending past said lateral apertures and a ringcarried by said nozzle-section and adapted to be moved longitudinallythereof for closing said apertures to a greater or less degree.

With this and other objects in view the invention comprises certainnovel constructions, combinations, and arrangements of parts, as will behereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a view in sideelevation of a nozzle embodying the features of the present invention.Fig. 2 represents a. longitudinal vertical central section taken throughthe same, parts being broken away and the parts being illustrated upon alarge scale.

In the present art attempts have been made to provide means forprotecting a fireman against the action of heat and flames, and Ipropose to accomplish this result in a most efficient manner by theemployment, in combination with a hose-nozzle, of means for producing alateral spray, means for varying the pressure upon said spray, and meansfor altering the thickness or width of the spray, whereby only a smallamount of water may be thrown laterally in front of the fireman as heenters a building, or a large quantity of water may be discharged aboutthe operator,

the quantities discharged being altered in degree corresponding, ofcourse, to the degree of exposure of the operator, provision being madefor permitting the regular streams to flow from the nozzle while thespray is in operation or for cutting off said stream, as may be desired.These desirable results are preferably obtained by the employment ofelements such as are delineated in the aocompan ying drawings, in which1 indicates any of the common forms of nozzle having its front ordischarge end internally threaded, as at 2, and being provided with anannular flange 3, extending outwardly from the outer surface at the rearend of the threaded portion. Just in the rear f the flange 3 areprovided apertures i d in the nozzle or nozzle-section 1, said aperturesbeing of any suitable number and of any desired size for permitting thedischarge of the required quantity of water. Here it is to be noted thatthe liange 3 produces a straight annular shoulder in line with the upperedges of the notches t, said straight shoulder extending for a portionof the width of the flange 3, said flange being formed with a beveledportion 5 beyond said straight portion. The nozzle-section 1 isexternally threaded, as at 6, just in the rear of the aperture i and asleeve 7 is threaded onto the portion 6 in po sition for being movedacross the apertures d. it will be observed that the sleeve 7 may bethreaded longitudinally of the nozzle-section 1 for increasing ordecreasing the space between the outer edge of said sleeve and the inneredge of the flange 3, the outer edge of said sleeve being formed with aflat portion corresponding to and extending parallel with the fiatshouldered portion of the flange 3 and the sleeve being further providedwith a beveled portion 8, extending beyond the flat portion and lyingparallel to the beveled portion 5 of flange 3, both beveled portions 5and 8 being disposed on an outward incline, whereby in operation waterdirected between th flange 3 and sleeve 8 will be given a naturalslightly-forward tendency in addition to its lateral. movement.

it is of course well known to those familiar a. cease-i with hydraulicsthat the discharge o1 liquids only one side of the plug is adapted toclose from a pipe through a lateral aperture is not l the bore of thetube-section 9 when the plug made with the same velocity with which thecurrent within the pipe is moving, and as it is desirable to at timesimpart to the spray moving between the flange 3 and sleeve 7 as great animpetus as is possible I provide a battle-plate for directing a certainproportion of the current within the nozzle-sections 1 through theaperture 4-, said bathe-plate comprising a section of tube 9, threadedinto the threads 2 and having the diameter of its bore less than thediameter of thenozzle-section 1, the lower or rear end of saidtube-section 9 extending across the apertures L and being beveledoutwardly, as at 10, for cutting the stream within the nozzle 1 anddirecting a portion of the same outwardly through the apertures a. Inthis connection it is to be noted that I preferably provide a bevel 11at the end of the bore of the nozzle-section 1. corresponding with andarranged approximately parallel to the bevel 10, said bevel 11 beingadapted to form a seat for the bevel 10 when the tube-section 9 isthreaded into the nozzle-section 1 to its i'ullest extent. Thus it is tobe observed that the tube-section 9 may be threaded longitudinally intoposition for completely closing the space between its rear end and thefront end of the nozzle-section, and the lateral discharge of water thusprevented, or said tube-section 9 may have its rear end spaced to anydesired extent from the bevel 11 of the front end of the nozzlesection1, whereby the degree of pressure upon the lateral spray may beeliectually controlled, the sleeve 7 serving to control the thickness ofthe spray being discharged.

A lock-nut 12 is preferably threaded onto the tube-section 9 in positionfor coming in contact with the outer end of the threaded portion .4 whenthe tube-section 9 is brought to its normal position, whereby said.tube-section may be locked in a given position by the tightening oi thethreads thereof, due to contact of nut 12 with the end of threadedportion 2. Thus the tube-section 9 may be set at given point andmaintained against displacementd u 1'- ing any given operation. The nut12 may of course be threaded for a suliicient distance longitudinally ofthe tube-section 9 for permitting said tube-section to close the spacebetween the beveled portion 10 and bevel 11 when desired.

An important feature of the present invention lies in the fact that 1provide a plugvalve 13, interposed in the length of the tube 9 andarranged for cutting oii the stream normally passing through the nozzle,the said valve bein positioned within the tube-section instead of withinthe nozzle-section for permitting the stream to be cut ofi while thespray is maintained. The bore of the plug 13 is disposed at one side ofthe plug, so that said plug may be of a minimum diameter, and

is turned to a closed position. Any suitable operating-handle 14. may beconnected to the valve 13 for facilitating the manual operation thereof.

In practice I have found that each of the webs or sections of materialseparating the several apertures 4 will ordinarily cause a break in thesheet of water being discharged laterally unless means are provided forpreventing such breach in the sheet of water. I find, furthenthat theinclined surfaces 5 and 8, extending at an angle with respect to thehorizontal surfaces of the flange 3 and sleeve 7, provide such means,and the presence of the angle in the annular groove produced between theflange 3 and the ring 7 effects a union of the water discharged throughthe apertures 4:, so that a continuous unbroken annular sheet isdischarged. 1. lind, further, that any angle formed in the said annulargroove will produce this e'dect; but of course i prefer the angleillustrated, as it has the additional advantage of giving the sheet ofwater discharged a slightly forward inclination.

Having thus fully described my invention, what i. claim as new, anddesire to secure by Letters Patent, is

1. A nozzle comprising a nozzle-section formed with apertures, anannular flange at one side of said apertures, and a sleeve at the otherside of said apertures producing a corresponding, annular flange,whereby an annular groove is produced between said. flanges, each of thecontiguous faces of said flanges being formed with an angle intermediateits width.
